Carbon Dioxide (CO2) is commercially produced from a wide
range of feed gas sources, i.e. ethanol fermentation, cogeneration,
refinery gas, natural wells, coal gasification, and ammonia production.
Each CO2 feed gas source and industrial purification process involves
a unique set of analytical challenges that must be met in order to
insure CO2 product quality. The analytical program that Atlantic
Analytical recommends to each client is designed to detect and quantify
the critical contaminants associated with their CO2. A well designed,
reliable analysis strategy ensures that all undesirable contaminants
have been monitored and reduced to acceptable levels for the intended
CO2 application.

and advanced tests employed by Atlantic Analytical to determine
CO2 purity according to USP/NF, ISBT, CGA, and other professional
standards as well as to meet specific industrial/beverage company
requirements:

Sulfinert® (SI) and Silcosteel® (SC) treated stainless steel
cylinders are being used for CO2 analysis. Pictured is a typical Sulfinert
cylinder
that has just arrived and is being quality controlled to ensure that the
correct amount of product has been received.

Pictured below are two levels
of standards that have been analyzed on one of the gas chromatographs
dedicated for Sulfur Speciation using a Sulfur Chemiluminscent
Detector (SCD). Not only can we determine total sulfur, but
we go one step further, and determine which sulfurs are present
and at what concentration down to a Limit of Quantitation
(LOQ) of 20 ppb. |
